原裝正品德國(guó)比例閥*銷售 德國(guó)力士樂(lè)REXROTH 力士樂(lè)比例閥 09

閥對(duì)流量的控制可以分為兩種：
一種是開(kāi)關(guān)控制：要么全開(kāi)、要么全關(guān)，流量要么zui大、要么zui小，沒(méi)有中間狀態(tài)，如普通的電磁直通閥、電磁換向閥、電液換向閥。
另一種是連續(xù)控制：閥口可以根據(jù)需要打開(kāi)任意一個(gè)開(kāi)度，由此控制通過(guò)流量的大小，這類閥有手動(dòng)控制的，如節(jié)流閥，也有電控的，如比例閥、伺服閥。
所以使用比例閥或伺服閥的目的就是：以電控方式實(shí)現(xiàn)對(duì)流量的節(jié)流控制（當(dāng)然經(jīng)過(guò)結(jié)構(gòu)上的改動(dòng)也可實(shí)現(xiàn)壓力控制等），既然是節(jié)流控制，就必然有能量損失，伺服閥和其它閥不同的是，它的能量損失更大一些，因?yàn)樗枰欢ǖ牧髁縼?lái)維持前置級(jí)控制油路的工作。力士樂(lè)Rexroth放大器
